The do_shmat function in ipc/shm.c in the Linux kernel through 4.9.12 does not restrict the address calculated by a certain rounding operation, which allows local users to map page zero, and consequently bypass a protection mechanism that exists for the mmap system call, by making crafted shmget and shmat system calls in a privileged context.

## Abstract
We introduce , a novel technique for automatically learning system
call filtering policies for containerized microservices applications. At
run-time, automatically learns which system calls a program should
be allowed to invoke, while rejecting attempts to call spurious system calls.
Further, addresses many of the shortcomings of state-of-the-art
static analysis-based techniques, such as the ability to generate tight filters
for programs written in interpreted languages such as PHP, Python, and
JavaScript. has a simple and rob
